Vermont Casting DTV38s2 installation instructions Hearth, Framing and Finishing, Final Finishing

Hearth

A hearth is not mandatory but is recommended for aesthetic purposes. We recommend a noncombustible hearth which projects out 12” (305 mm) or more from the front of the fireplace. The hearth cannot exceed 1¹⁄₂” (38 mm) in height from bottom of fireplace for ease of door accessibility. (Fig. 4)

Cold climate installation recommendation: When installing this unit against a non- insulated exterior wall or chase, it is

mandatory the outer walls be insulated to conform to applicable insulation codes.

3.	Frame the fireplace with a header across the top of
	the standoff. (Fig. 5) It is very important to allow for
	the finished wall face along with marble, tiles or any
	other noncombustible face finish material desired
	when setting the depth of the framing.
4.	Attach the fireplace nailing flanges to the frame as

are positioned 1” (25mm) back from the face of the unit. NOTE: The U-channel depth can be adjusted by loosening the hex nut inside the channel.

If marble, tile or any other noncombustible decora- tive face finish material is desired, a 3” (76mm) wide noncombustible board (recommended Dura-Rock) is to be nailed to the nailing flanges on both sides of the unit. Also, 12” (305mm) of noncombustible board is to be nailed to the front face of the U-chan- nel and the top framing member above the standoff.

Combustible material can then be brought to the outside edges of the noncombustible board installed earlier. Any noncombustible decorative face finish could be brought to the sides and top of the unit and can cover the framing and sheet rock. If a decora- tive facing is not desired, then the noncombustible boards must be double thickness and brought flush with the face of the unit.

Final Finishing

Noncombustible materials such as brick or tile may be brought to the edges of the face of the appliance.
